2 weeks process and things flow very well. If they like you they make sure to let you know and you would hear back very soon....It is a great place to work for and usually big companies take time to hire.
I applied through an employee referral. The process took 5 days. I interviewed at IBM (Sydney) in Jan 2010
Interview
I had a few face-to-face interviews, but the big one was a panel interview. I had four people sitting on the same side of the table, opposite of me. They each had their own "script" that had specific questions. They continuously peppered me with question after question.
